BPC Homes Earn Exceptional HERS* Scores

*Home Energy Rating System (HERS) is a national standardized method for comparing home energy performance.  It is based upon energy-related factors, including insulation, windows, mechanical systems, and a blower door test for air tightness.

2004 to Current: LOWER HERS Scores are Better

green home in Connecticut by BPC Green buildersA HERS score of 0 (zero) means the home either uses NO energy from the power grid or makes as much (clean) energy as it uses from the power grid netting out to a Zero use of power from the power grid.

A negative HERS score means the home generates more energy than it uses from the power grid.

In most places in our service area, homeowners receive credit for the clean energy their home puts into the power grid, offsetting the cost of the power they may use. This can result in as low as zero power grid energy costs for the homeowner.

Bolded Projects in this table are Zero Energy Ready Homes, LEED for Homes, Passive House or better
Bolded Projects in Green are Net Zero Energy Homes or better

LOWER HERS Scores are Better

A zero (0) HERS score means the home is a Net Zero Energy Home. A negative HERS score means the home is a Positive Energy Home.

Please note that BPC homes built before the ones on this list had HERS scores based on the old and no longer used HERS scoring system that resulted in scores that can’t be easily compared to the new system. The homes built before were therefore not included in the above chart to avoid confusion.

Zero Energy Ready Homes must also be ENERGY STAR and Indoor airPLUS Certified. Some are also Water Sense Certified. Passive House homes are also Zero Energy Ready. 

** Percentage improvement over normal (model) building code. Note that the amount of energy required to heat and cool a BPC home versus a house built to code is generally reduced by a significantly greater percentage than indicated by this statistic.
